Effect of anisotropic conductivity of Ag2S-modified ZnmIn2S3+m (m = 1, 5) on the photocatalytic properties in solar hydrogen evolution

The anisotropic carrier transport property of Ag2S/Zn5In2S8 is substantially stronger than that of Ag2S/ZnIn2S4, resulting in higher bulk carrier separation rate and photocatalytic hydrogen evolution performance of Ag2S/Zn5In2S8.

Abstract Carrier transport properties of ferroelectric Hf0.5Zr0.5O2 (HZO) thin films have been investigated on metal-ferroelectric-metal (MFM) capacitor in the first current flow of ferroelectric poling treatment. In current–voltage (I–V) measurement of MFM capacitor, a kink or discontinuity point of derivative in I–V characteristic appears, and after the cyclic voltage sweep this kink disappears. This phenomenon is different from the ferroelectric instabilities after several thousand or million voltage cycle applies reported as the wake-up and fatigue. From the analysis using Poole-Frenkel plot of I–V characteristics, it is suggested that irreversible trap generation by electric field apply occurs in poling treatment.

Effect Of Particle Size

Rod-like La5Ti2CuS5O7(LTC) particles with larger sizes generate a higher photocurrent owing to lower densities of defects and grain boundaries interrupting the spatially separated carrier transport.
